A 240 kilograms object and a 540 kilogram object are separated by 4.40 meter.
(a) Determine the magnitude of the net gravitational force exerted by these objects on a 70 kilogram object located midway between them.
(b) Find at what position (other than an infinitely remote one) can the 70 kilogram object be located so as to experience a net force of zero from the other two objects?
